    Hi. I have been asked to make an illuminated sign to go on this building…hope the photo posts as intended –

    The tower is 7 meters in diameter, and the sign will be a circular illuminated sign measuring about 2.4m in diameter.

    Being on a curved wall makes everything quite complicated. A box following this curve would be really hard to make.

    Does anybody have any ideas as to how this should be done?

    Or should I just tell them its too hard, and why not just put a couple of lights on that verandah, and the sign can be made from curved signex, acrylic, or even just a vinyl decal?

    Hi Brian

    This is literally 5 minutes of guesswork, but just posting it to give you some feed for thought, mate.

    If this was me, I would outsource the fabrication to a trade “flexface” sign company.
    My preference is the SignComp system due to its ease install. (Global Brand)
    Give them the building dimensions and all else and they will send you a sign ready to install.
    At this sort of size sign, the flexface would most likely come in two half sections.
    You fix the prebuilt frame/box to the wall, run a power cable to it and illuminate it.
    Next, install the face skin using the skin tension arm.

    I have attached very crude visuals based on the sizes you gave.
    when I scale the front view of the building up, the sign circle looks out of proportion in your visual.
    The black panel I show indicates an 80-inch door entrance. when the photo is scaled to this and a 2400mm circle is applied, you can see a significant size difference.

      Thanks Rob, your comments are very helpful.
      Actually the entrance is 3.6 metres wide, which is the same width as the distance between those two vertical lines running up the front , so the 2.4 diameter circle would not be nearly as big as your drawing shows. My drawing is correct.

      Anyhow, on pondering this I think I will respectfully decline this job, I may try to find somebody to take it on, but NZ is not structured the same way as the UK, specially here in the boonies of the south island.

    Access Problem.
    Access above that canopy will be a problem. I doubt you will be able to work on top of it.
    I also doubt a cherrypicker will be much use trying to get in close enough or low enough above the canopy. Just some things to consider!

    Based on a 7000mm building radius, and a 2400 sign.
    there is an approximate 200mm elevation of the sign on either side.

    ( Note, sizes are guesswork based on these illustrations, do not go by these )

    An example of a flexiface sign illuminated.

    To properly make one of these, the fabrication will be out of your hands. so the trade supplier makes the whole thing.
    And to be honest, the installation could become a nightmare trying to gain access to that area, so I think it may also be wise to ask the trade supplier if they can suggest an installer in your area, to take on the whole installation.

    At the end of the day, It is all very well for me to say do this and that, but I have installed lots of large flexiface signs over the years. so it may become a bit of a daunting task when all aspects are taken into consideration.

    Thank Simon

    Yes, you are correct mate, I have just scaled it up using your door width dimensions.
    Whereas I was “guessing the height of the door” and scaling up from that! 😀

      It takes a real man to admit a mistake!
